Crushed sand with a grain size of 0/4 to 0/10 should be used for Stabilizer surfaces. The percentage of fine grains (below 80 microns) should only amount to 15 – 20 %. The sand must be weather resistant. Glass sand is not suitable.
A particle-size distribution curve must be established for unidentified sand. We also recommend that a sample is produced in order to determine the colour and granulometry.
- Conventional, water-permeable compacted hardcore.
- Required subgrade +/- 2 cm
- Pure subgrade is only necessary if the height varies by more than 2 cm.
- Where the hardcore does not meet water-permeability standards, a pure subgrade consisting of coarse and fine chippings should be laid.
- The sand must be mixed well with Stabilizer, to achieve a uniform consistency
- 6 kg of Stabilizer must be added for each tonne of material.
- The mix must be moistened (earth-moist).
- After installation, a sprinkler should be used to wet the surface until the water has soaked into the entire Stabilizer layer.
- A 800 – 1000 kg tandem roller should be used to repeatedly structurally compact the surface.
- The surface must not be subjected to vibration.
- The surface can be cleared for use once it has dried out. This may take between 3 and 15 rain-free days, depending on the time of year.
- A small quantity of loose grains will remain on the surface after a few weeks of use.
Stabilizer is a natural material used to stabilise areas subject to erosion.
It is a 100 % natural resource.
Stabilizer is the brand name of a product made from finely ground grains of the Psyllium plant.
The raw material is grown by farmers in semi-arid and arid areas of the South West United States.
Stabilizer is produced from extensively cultivated areas and not from plants growing in the wild.
Products for medical applications are also produced from the same plant.
The plants are dried and ground in mills and then sieved to achieve a uniform consistency.
Stabilizer is not water-soluble and has a characteristic odour. It forms a gel when combined with water.
Stabilizer should be handled in the same way as cereal dust. The dust must not be inhaled and skin should be washed with water if it comes into contact with the powder. Dust masks must be worn when working with Stabilizer.
